This Amendment No. 10 to Schedule 13D (this “Amendment”) amends and supplements the Schedule 13D initially filed on August 29, 2014, as amended and supplemented by Amendment No. 1 thereto filed on June 23, 2015, Amendment No. 2 thereto filed on -----August 2, 2017, Amendment No. 3 thereto filed on June 26, 2019, Amendment No. 4 thereto filed on February 6, 2020, Amendment No. 5 thereto filed on February 13, 2020, Amendment No. 6 thereto filed on August 31, 2020, Amendment No. 7 thereto filed on February 5, 2021, Amendment No. 8 thereto filed on May 26, 2023 and Amendment No 9 thereto filed on October 11, 2023 (as so amended and supplemented, the “Prior Schedule 13D” and, as amended and supplemented by this Amendment, this “Schedule 13D”).

This Amendment is being filed in part to reflect a greater-than-1% decrease in the Reporting Persons’ previously reported beneficial ownership percentages as a result of an increase (prior to giving effect to the Reverse Stock Split) in the number of Shares outstanding, as reported by the Issuer in its Form 10-K filed with the SEC on April 4, 2024.

Capitalized terms used without definition in this Amendment have the meanings ascribed thereto in the Prior Schedule 13D.

Preliminary Note

Capitalized terms used in this Preliminary Note without definition have the meanings ascribed to them elsewhere in this Schedule 13D. 

On May 2, 2024 the Issuer effected a 1-for-24 reverse stock split of the Shares (the “Reverse Stock Split”), as reported by the Issuer in its Form 8-K filed with the SEC on May 1, 2024. The amount of securities beneficially owned reported herein has been adjusted and approximated to reflect the Reverse Stock Split.

Securities Holdings Resulting in Current Beneficial Ownership of Shares

As of the date hereof: (i) the Jack W. Schuler Living Trust (the “Trust”) holds 63,789 Shares; (ii) the Schuler Education Foundation (the “Foundation”) holds 1,416 Shares; (iii) the Trust holds Series B Warrants (the “2019 Series B Warrants”), issued on November 19, 2019 and expiring on May 19, 2027, which are currently exercisable (after giving effect to the Reverse Stock Split) for a total of up to 16,432 Shares; and (iv) the Trust holds Common Stock Warrants (the “August 2023 Warrants”), issued on August 15, 2023 and expiring on August 15, 2028, which are currently exercisable (after giving effect to the Reverse Stock Split) for a total of up to 31,875 Shares.

The 2019 Series B Warrants and the August 2023 Warrants (together, the “Exercisable Warrants”) are exercisable within 60 days of the date hereof.  Accordingly, pursuant to Rule 13d-3(d) under the Exchange Act, the Trust currently is deemed to have beneficial ownership of the aggregate 48,307 Shares acquirable upon exercise of the Exercisable Warrants held by the Trust.

Securities Holdings Not Resulting in Current Beneficial Ownership of Shares

In addition, the Trust holds Common Stock Warrants (the “May 2023 Warrants”), issued on May 5, 2023 and expiring on November 6, 2028, which are currently exercisable (after giving effect to the Reverse Stock Split but subject to the Beneficial Ownership Limitation) for a total of up to 13,982 Shares.

The terms of the May 2023 Warrants provide that May 2023 Warrants may not be exercised if, after such exercise, the Reporting Persons would beneficially own, as determined in accordance with Section 13(d) of the Exchange Act, more than 9.99% (or, at the election of the holder and after 61 days’ advance notice to the Issuer, 19.99%) of the Shares then issued and outstanding (the “Beneficial Ownership Limitation”).  As of the date hereof, the Beneficial Ownership Limitation (which, as applied to the Reporting Persons, is 9.99% as of the date of the filing of this Amendment) does not permit the Trust to exercise any portion of the May 2023 Warrants.  In providing the beneficial ownership information set forth herein, the Reporting Persons have assumed that, due to the Beneficial Ownership Limitation, none of the aggregate 13,982 Shares underlying the May 2023 Warrants are acquirable by the Trust.

Item 5Interest in Securities of the Issuer
